The Extech RD300 is an easy to use refrigerant leak detector with a heated diode sensor that will detect all CFCs, HCFCs, and HFCs refrigerants including R-22, R-134a, R-404a, and R-410a.  Service technician will find this RD300 refrigerant detector ideal for locating leaks in air conditioning and cooling systems that use standard refrigerants.

Key Features:
  • Detects all CFCs, HCFCs, and HFCs refrigerants
  • Field replaceable heated diode sensor
  • Sensitivity levels of High/Medium/Low 0.25/ 0.50/ 0.99 oz. /year
  • LED light at the probe tip (replaceable)

The RD300 refrigerant leak detector has a sensitivity ranging from 0.25 oz. /year on high to 0.99 oz. /year for low.  A technician can easily adjust the sensitivity level by pressing the sensitivity range button on the keypad when trying to locate the exact location of a leak. The green, yellow, red multi-colored LED bars on the keypad indicates the concentration of gases the instrument has detected.  When the leak detector has detected refrigerant it will emit both a visual and audible alert. However, a technician can mute the audible alert, if desired. The refrigerant leak detector also has a reset button to reset the meter to the ambient air to pinpoint a leak.

The flexible probe is 18” long and includes a LED light at the end to make it easier to work in areas that are dimly lit. The probe’s LED light can be turned on and off by a button on the keypad. The RD300 is operated with a 9V battery and will automatically shut off after 10 minutes of inactivity.  The keypad LOW-BATT light will switch on when the battery is getting low.  The instrument also comes with a leak test bottle to ensure the instrument is testing acurately.

Extech RD300 includes:
  • RD300
  • 9V battery
  • Leak test bottle
  • Protective hard carrying case
  • Instruction manual
